I. Introduction
I use the millet bracelet for quite a long time. I just came out from the first generation to the later version of the Sense of Light. I have started using it and I have used it for a long time. As shown in the figure below, my "millet movement" APP is too revised. So much that I couldn't find the total number of days of use. I only saw the following three data. It should be almost two years before the full play. The goal is 8,000 steps per day, but the actual number of days that can be achieved is only 207 days. Basically, this is The standard is that I have a running workout on that day. If the normal commutes go to work, they will not exceed 7,000 steps. Sometimes if you drive a car, it is estimated that there are only two or three thousand steps. However, if you run, it will basically exceed 16,000 steps, so the average daily pace exceeds 7000 steps, and the total number of kilometers is 3032.
For so long, what I want to say is that if the LCD screen can show time, then it would be perfect. So this time it was selected to evaluate this happy Mambo Watch.
Second, out of the box:
Below the box photos, introduce the product appearance, packaging, details
The packaging is very simple, it is a table, a product description, mainly because the watch is a straight-in standard USB interface
There is an introduction for the first time on the watch screen. This is necessary because there are no buttons on the whole body.
The whole body does not have any buttons
Back heart rate section
USB interface, once the form can be pulled down, remember to use force, so do not be afraid to fall when wearing or exercising.
Only one side is a standard USB interface and the other side is not.
Take a look at the effect of the wife's thin arm, she wears the millet bracelet with a light version, and she can't live with the smallest size, so the heart rate doesn't work for her, but it's perfectly fitting to wear.
Let's look at my thick arm again and use the penultimate fourth hole to fit.
The following boot, I use the millet mobile power, easy to take pictures. Just insert, um, right, insert, and boot. 
Since it's plugged in, it's fully charged. After all, the evaluation time is limited, and you can test it directly.
The default time of booting, when linked with the mobile phone APP, will automatically update to the mobile phone time;
Backside heart rate glow green, by the way, green LED represents continuous monitoring of heart rate, it will consume more power, and apple watch is green, and red, it is monitored every 10 minutes, if you monitor the heart rate is fast due to exercise Change, switch to green monitoring;
Third, mobile phone APP
There are two-dimensional codes in the product manual that can be installed to scan and install the mobile phone APP. I use the iphone 6S+. There is also a dedicated two-dimensional code for binding. Let me play a code.
After installing the app, I logged in directly with WeChat, and then made some personal information settings;
Turn on Bluetooth, and then add a smart bracelet, scan the second QR code in the above instructions can be bound;
There are operating guidelines to help you quickly get started
There is also an introduction to heart rate and exercise intensity to help you control the heart rate in the rhythm of the sport
Let's take a look at the settings of this watch. When the watch is connected, it will show the battery information. This is my second charge, and it will use the third day, and there will be 40%. The alarm clock setting, like the millet bracelet, sets up at most 3 alarm clocks, which is basically enough.
Sedentary reminder, this can be set according to your preferences;
Target setting, the default is 7000 steps, millet bracelet with a long time, accustomed to 8000 steps per day, changed; In addition, there are target weight is 67 kg, but did not say, can only see.
There are also points, 1000 points for 1 point, but do not know what the points are used to do, the products in the mall can not be used to redeem the points.
Finally, you can also make a suggestion
Fourth, the use of watches
The first screen of the watch, showing the time, date, and week, is basically clear;
The second screen (sliding the screen from right to left), this is exercise, press the lower right corner
Heart rate monitoring
This is the state of exercise, the first number of steps, how many calories burned in the second one, and the third distance in kilometers. This is calculated based on the default squat, but it cannot be modified in the APP.
WeChat message, vibration reminder, can not open to see the specific message content.
Caller ID, you can answer the phone, but personally feel that there is no need to, as long as you can remind it, answer the phone, or to use the phone to be considered. If you have a quick button to hang up, it's more practical than answering the phone.
All of the above photos were taken indoors. The effect of the display screen was not so good outdoors. It is still clear to see in the shade.
But the effect in the sun is not so good.
Raise your hand to brighten the screen, posture is very important. When the gif was taken, there was just a low battery, so first remind the battery is insufficient, and then to the normal display of the first screen, if the battery is fully charged, the battery will not appear as the first screen.
Waterproof performance also tested, soaked in water, short time is not a problem
Swiping the screen inside the water is useless because the capacitive screen cannot operate underwater.
The following shows the situation under exercise conditions. The second screen running icon, point the arrow in the lower right corner to enter the sport mode, and then click on the play icon in the lower right corner began, the lower left corner is the return icon, this we all see to understand. The top is the display time, the middle is changeable, heart rate, number of steps, calories, etc. can be displayed. I choose the heart rate by default. When I exercise, I look at aerobic exercise.
Below and the millet bracelet light feeling version, as well as the smart smart watch on the running sports to make a comparison, mainly to see if the heart rate is accurate.
When I was running, I received Xiaomi mobile phone voice broadcast heart rate exceeded, just on the side street lights, so I looked at it (in fact, the watch has a night light, but in order to take pictures, have to find a street lamp, will be clear), found Millet wristband monitoring heart rate is 166, Garmin is 161, but happy heart this only 139, the former two are not much difference, and the latter is a bit far from the gap.
Then I walked for a while and looked at another street lamp. At this time, the millet bracelet was 137, Garmin 133, and the music was 140. Now the three are almost the same. Under this streetlight, I observed a long time because I stopped and my heart rate gradually decreased. At this time, the gap between the three is not big, basically around 5. But during the running, I observed that my heart rate was more than 20 lower than the previous two.
After watching the average heart rate after exercise, millet bracelet is 122, smart heart smart watch 117, Garmin smart watch 129, a bit of a gap.
V. Summary
After about 10 days of trial (June 28-July 7, yes, more than the deadline), as a former product manager, I defined this smart watch as a "basic model." In other words, some of the functions are basically there, but there is still room for improvement and upgrading.
1. In terms of size, no matter whether it is a big man with a thick wrist or a small woman with a small arm, there is no problem;
2, USB interface directly into the charger is still very convenient, this is praised. Unlike millet and Garmin, there is a dedicated data line to charge. When Garmin came out the door once, he reminded him of low battery power. The result was no electricity in the afternoon (now he knows that when the low battery is reminded, he will turn off his heart rate, and there is no problem if he supports more than 1 day).
3, in terms of message notification, WeChat, SMS, and caller will all vibrate and remind, but I think the light reminder is not enough. Touching the screen can see the message content is still available. I don't know whether this can be achieved by updating the firmware. Which APP notifications to choose from and which do not need to be reminded, because now they only remind WeChat SMS calls.
4, heart rate, this I personally recommend to increase the off setting, after all, usually do not need this feature, you can close to increase life. This is what I am using.
5, battery life, before and after 10 days, after full power can be used for 4 days, the fourth day began to remind low battery, but can be used at night, no electricity, no time display the first screen, but shows no electricity, this should be compared Quasily, because it takes four days for two charges.
The above is my own evaluation report. If I can help you, I will be very happy. Thank you for watching.
